When your furnace is operating properly, it should give warm air without creating too much noise. While it’s common to hear your furnace making noise as it starts up, other noises are showing your furnace requires immediate professional help.
Here are some of the most frequent furnace noises and what they could mean. If your furnace is making a strange noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Swanton, Ohio.
1. Furnace Making a Banging Noise
You may have a serious situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a few problems. These include gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy over the years, so that’s why it’s important to set yearly furnace maintenance with Northwest Services. One of the tasks our pros complete during this service is clean your furnace’s burners. When this component gets grubby, you might hear your furnace making a loud rumbling noise after ignition takes more time. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can emit carbon monoxide, which is normally emitted outside. This toxic gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Northwest Services advises turning it off and contacting us at 419-548-5017. Excessive natural gas in your furnace or a fractured heat exchanger are critical troubles that should get prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide warm air across your residence. If the ductwork wasn’t designed properly or is getting dated, it can be noisy when your furnace is heating. This could be the case if your furnace makes a banging noise when it shuts off. Get in touch with Northwest Services at 419-548-5017 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the right voltage. If wires or the box isn’t tight enough, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends hot or cold air throughout your space, and a capacitor, which turns on the motor. If either of these components are fading, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be related to something little, like an unsecure screw, or something major, like a broken part. In either case, we advise shutting your furnace off and calling our heating specialists at 419-548-5017 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to alert you it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing could need to be lubricated. We realize that maintenance sometimes slips your mind, but our professionals can get your furnace operating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You could also hear whistling while the furnace is working if a floor vent is loose. If you’ve checked your vents but are still sensing sound, Northwest Services can provide support. It’s essential to get loose ductwork repaired fast, because it can result in comfort problems in your house and inflate your utility bills.
6. Furnace Making a Grinding Noise
It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal sound usually means there’s a problem with your furnace’s blower. Switch off your furnace off immediately and contact our pros at 419-548-5017 for assistance.
